I didn't do my 2010 taxes because the unemployment department gave me a 1099G that claimed I received a few thousand more than I actually did, causing me to owe taxes when I shouldn't have. I didn't feel like dealing with it, so I never did my taxes for that year, which snowballed into not doing 2011's taxes, but I should've gotten a refund, not owed for that year also.
Now I'm playing catch up and e-filed my 2012 taxes, while also sending my 2011's taxes by mail. It's been a few days since the IRS accepted my 2012 taxes, but they haven't deposited any money into my bank account. Now I'm getting worried they might withhold it until I finish 2010's taxes, which might take me months to resolve the 1099G issue at the rate the unemployment dept goes.
